IMPROVEMENT IN PARLOR-ORGgANS.

Specification forming part of Letters Patent No. 110,900, dated January10, 1871.

To all whom it may concern:

Be it known that I, JAMES CORDLEY, of the city of Adrian, in the countyof Lenawee and State of Michigan, have invented certain Improvements inParlor-Organs, of which the following is a specification.

My invention relates primarily to a simple and practical parlor-organ otthe combined reed and pipe type.

The first part ot' my invention consists in a peculiar construction andrelative arrangement of the several bellows of such an organ and theirconnections. y

The second part of my invention consistsin a peculiar combination ot'devices for operating a pair of vertical pumping-bellows without the aidof springs or weights by the alternate depression of two pedals.

In the accompanying drawings, Figure 1 is an end elevation ot' acombined reed and pipe parlor-organ embodying my invention. Fig. 2 is avertical section of the same, cutting the cord e in Fig. l. Fig. 3 is afront elevation, showing the keys K and pipes P.

D is the inclosing case of the instrument.

A and A' represent the two front blow-bellows.

B is the exhaust-regulation bellows.

C is the additional wind-regulation bellows for blowing the pipes.

H is the reed wind-chest, and 'i a wind-conductor from the reedwind-chest II to the bel- ]ows B.

l is a similar conductor from the bellows C to the pipe wind-chest a.

7c is the valve-pin to operate the valve in the wind-chest n, whichvalve is not represented in the drawings.l

c is the reed-valve, held over the opening in the ceiling of thewind-chest H by the spring y.

The pedals a and a are made to operate the front blow-bellows, A and A,by means of the cord c, attached to the depressed pedal a and 'passingup over the pulley c, and ott' horizontally, is'made fast to the uppercorner ot' the bellows A, then around the horizontal pulley c, thenfastened to bellows A', then outward to and over the pulley c', andthence downward and secured to the now elevated pedal a', so that as oneof the pedals is borne down the other is drawn up by the cord c', andvice versa, thus .dispensing with the spring commonly used for thepurpose of throwing the pedals up. Nothing is claimed to be new aboutthese pedals themselves; nor about the keys K or key-frame U, reeds g org', reedboard m, bellows A, A, and B, and therefore I deem any furtherdescription ot' their construction unnecessary.

The valve w ofthe supplementary wind-regulation bellows C is a tlatvvalve hung at the upper edge over the opening and connected to the backot' the said bellows O by means ot' the string s, the object ofthestring being to draw the valve open when the said bellows C issuflieiently iniiated.

The valve o of the main wind-regulation bellows B is similar in form andhung the same, having a small spring to hold it shut, and a pin, r, topush it open when the wind is eX- hausted.

Operation: As the pedal a is pressed down the bellows A is drawn open bythe cord c and inated with air drawn from the bellows B through thevalve t until the valve u is thrown open by the keys, when the airrushes in through the reeds7 causing them to speak, and filling theexhausting-bellows B. As the other pedal, a, is pressed down and thebellows A drawn open, the former bellows, A', is drawn shut by the cordc, closing the valve t and forcing the wind down through the valve b andchannel d into the bellows U, causing it to be inated until the string sdraws the valve w open, the wind in the meantime passing up through thechannel Z into the pipe wind-chest n, causing the pipes and reeds tospeak, each bellows contributing alternately to this object.

In place ofthe pedals, the ordinary hand-lever may be used, itdesirable.

I have also contemplated locating the additional bellows G4 horizontallyin the space I) below where it now is, and placing the pipes all in thecase below the keys.

I am aware that a pair of horizontal exhausting-bellows in a Frenchorgan have been so connected that the depression ot' one pedal to openits bellows closes the other bellows and raises the pedal thereof. I donot therefore claim broadly so connecting the pedals ot' a two-bellowsorgan that the depression ot' one pedal elevates the other, but limitmyself to my specitic devices for applying said function to a two-pedalvertical bellows-organ.

I claim as my invention-- 1. In the described organ, thepumping-belcords e e', vertieal pulleys c c', and horizontal lows A A',reed bellows or regulators B, and pulley c for operating the saidbellows withpipe bellows or regulators C, wind-stocks 15 d l, out theaid of springs. reed windebest H, and pipe wind-chest n with valves t bo w, constructed and arranged as shown and set forth, for lche purposespecified. Attest:

2. The combination, with the vertical pump- N. B. FASSETT, ing-bellows AA', of the pedals a a', connected J. R. M GELDOWNEY.
